Also...while I won't tell you to go on a buying spree of all those upgrade parts for your current computer... I am told that you could (if you're thrifty and resourceful--AND do all your own homework on the issue) build pretty sweet a custom gaming computer--and I'm told spend no more that 1.5K at the most.

The machine I have cost me 350 Great British Pounds, it plays the latest games at very high.

If you do your homework, research the current market ect. You can build a descent gaming rig very cheap.
